solves the big battery problem

Samsung is planning something big. The company has been releasing scalable products for a few years, but that ends in 2025, with the launch of several Samsung devices that have the potential to change everything. And the patents filed by the company will have great weight in this “return of the king”.

In recent weeks, several patents filed by Samsung have been made public, focusing on advances the company's engineers are making in things like flexible displays or new types of devices like tablets with rollable screens. The latest patent made public will concern foldable cell phones, in particular their battery.

Until now, all foldable phones had a similar interior design, basically the only one possible. Although a foldable mobile phone looks like a large device to the user, In practice these are two 'blocked' deviceswith independent parts connected by cables. Space management is therefore very important, especially in an essential element like the battery.

The Galaxy Z Fold actually has two independent batteriessmaller than the battery of a traditional mobile phone. This is a smart solution, requiring some engineering and a lot of work in “software” battery management; but this has its disadvantages, particularly with regard to the capacity of the batteries and their thickness, since having two batteries the thickness can be double, depending on whether they are single-cell or multi-cell batteries.

The logic would be to use a multi-cell battery, to take advantage of its greater capacity, which is necessary when using larger screens which consume more. If the manufacturer chooses a single-cell battery instead, the thickness will be lessa much more important aspect than in a classic cell phone because basically, when we close a foldable phone, we put two cell phones on top of each other; but in doing so, the manufacturer is making a sacrifice in terms of overall capacity that no current user will accept.

Samsung may have found the solution to this conundrum: a flexible single-cell battery. Indeed, the idea is that the battery extends throughout the device, and that it folds with the screen; This way the cell will take up enough space to store enough energy for a modern foldable. As usual, just because Samsung filed this patent doesn't necessarily mean it will use it, but it wouldn't be surprising if the company uses this technology in its future foldable phones.
